2 doc.: IEEE /0150r1 Submission Jan 2015 Ganesh Venkatesan (Intel Corporation)Slide 2 Abstract Describes a GLK-GCR which is a simplified GCR service for GLK.

3 doc.: IEEE /0150r1 Submission AP functions A GLK-GCR Service is setup for every SYNRA –What is the choice of retransmission policy? Block ACK when SYNRA represents a small (< 10) GLK STAs; unsolicited retries, otherwise. –AP implicitly does the GLK-GCR Service setup for each SYNRA which may be modified if the AP decides to move between Block ACKs and Unsolicited Retries [Re]Association response include the GLK-GCR Response element –may also include a BA Agreement element if the GLK-GCR retransmission policy is BlockACK Notifications can be groupcast to all affected GLK STAs using current GLK-GCR retransmission policy –Useful when GLK-GCR retransmission policy changes Jan 2015 Ganesh Venkatesan (Intel Corporation)Slide 3

4 doc.: IEEE /0150r1 Submission AP Functions If one or more GLK STAs go into PS mode, the AP will not buffer GLK-GCR frames destined to those GLK STAs –But send the corresponding frames as unicasts to the GLK STA. Jan 2015 Ganesh Venkatesan (Intel Corporation)Slide 4

5 doc.: IEEE /0150r1 Submission GLK STA functions Set internal state based on the contents of the GLK- GCR Response element in [Re]Association Response frames and in that include a GLK-GCR Response element –Handle corresponding GLK-GCR frames received appropriately Drop duplicates, respond to BARs, etc Jan 2015 Ganesh Venkatesan (Intel Corporation)Slide 5
